Micron-sized colloidal crystals comprised of gold nanospheres have been synthesized directly from a gold nanoparticle/methyl methacrylate colloid by application of a 514 nm laser at 500 mW. An array of colloidal crystals ...

A large number of thresholding methods exist. These methods perform differently in various image analysis problems where they are often used locally. They are not as effective globally. Global thresholding is a difficult ...

Using the discrete dipole approximation (DDA) the local electromagnetic fields surrounding gold nano-cap particles are investigated. Suitable k-vectors and polarization vectors of the incident light are used to determine ...

n this paper we introduce a mathematical modelling of signal which is considered to be received from the near-field of an arbitrary antenna array. The signal model of our formulation is almost similar to beamspace processing ...

This paper aims to compare different location management techniques and their suitability for adaptation in the next generation wireless IP networks. It is found that in a macro-mobility environment, the pointer forwarding ...

Near Field Magnetic Induction Communication (NFMIC) is emerging as an appreciatively beneficial physical layer access method in short range communication. Although it provides more secure, robust and power efficient system ...

Radio frequency spectrum mapping allows determining the radio frequency signatures prevalent within an environment. We address the primary frequency bands used for cellular, wireless Local Area Network (LAN), Universal ...

The optical response from metal nanoparticles and nanostructures is dominated by surface plasmon generation and is critically dependent on the local structure and geometry. Electron energy-loss spectroscopy (EELS), combined ...

Conductor-insulator nanocomposites in which the conductor percolates can have optical responses at longer wavelengths like dense conductors with an effective plasma frequency wp*. This applies at wavelengths where the ...

In-home healthcare applications that use wearable devices ordinarily have strict power constraints due to the small size of the battery in the device. The power constraints are a key driver of research to develop new methods ...
